Gold vessels found in a Scythian burial mound in the Caucasus Mountains near Strovopol, southwestern Russia, have traces of cannabis and opium inside them.
The artifacts were discovered in the summer of 2013 when kurgan Sengileevskoe-2 was being excavated in advance of power-line construction.

An act of warfare is portrayed on the other side of the bowl-shaped vessel. A Scythian warrior fires an arrow at a foe, while another lies dead and beheaded at his feet.
